Jack Tatum, Park County's director of homeland security, said the problem is how dry the area is currently.
"With the rain in a very quick amount of time, we could be looking at the potential for a large amount of runoff, not a lot of soaking in the water," said Tatum. "Or we could be looking at some mudslides and rockslides and some potential for flash flooding."
But he said nobody needs to panic. His department is making sure everything is ready if any action needs to be taken.
"That would be where I'd make a call to activate our folks, with our community emergency response team to assist with sandbagging," he said. "And also give our folks at the road and bridge shop a call and say that I would need some sand dropped in a certain location so that we could start filling sandbags there and get them into the right places."
Tatum said the National Weather Service will warn his department if there is any possibility of these conditions.
